I sometimes use my touchphone in the bath. I know it’s stupid. One problem I encounter is that when put my left hand in the water without thinking, it gets wet and unusable for touchscreen navigation. It is too risky to try to hold and navigate with one hand. I found that I could use my nose to scroll but I couldn’t see where my nose was touching precisely. It was at that point that I came up with this idea of a nose extension ‘finger’ that would allow navigation while my phone is firmly held by one hand.
